I'm having an issue with the screen resolution in the Steam version of the game. When I set the resolution to 1080p, my display's resolution, the game window is almost twice as large as it should be i.e, the edges of the game window are outside the edges of my screen. This is hard to explain, so here are some images:

The image when I set the game resolution to 1080p (my native resolution):

The image when I scale the resolution down to 720p (it fits properly):

Basically, the issue seems to be that FS15 thinks 1080p isn't 1080p, or is scaling up the image for some reason!

All my graphics drivers are up to date. I ran this game on my previous computer, the screen of which had a resolution of 1360x768. Could Steam be saving some data about my PC, and think I'm still running on my old system or something? Just a thought.
